Description

refrigerator

The present disclosure relates to a refrigerator in which a plurality of storage containers are configured to be pullable from a storage compartment provided in the refrigerator body.

The refrigerator has a plurality of storage compartments such as a freezer compartment and a refrigerator compartment inside the refrigerator body. The location of each storage room is usually determined according to the purpose of each storage room. The extra large storage compartment on the lower side of the refrigerator is configured such that a storage container with an upper surface opening is pulled out and pushed into the refrigerator body or the storage compartment in conjunction with the opening and closing of the drawer door. At this time, the storage container is often divided into a plurality of sections along the up and down direction, and it is not uncommon for the storage container to be divided into three sections: upper, middle and lower. Moreover, the handle of such a drawer door is arranged on the upper side of the drawer door.

As an example of a refrigerator that accommodates three-stage storage containers in an upper, middle, and lower compartment, there is a refrigerator described in Patent Document 1, for example. In the refrigerator described in Patent Document 1, a pair of brackets are respectively fixed to the left and right sides of the inner surface of the drawer door, and the first storage container is arranged on the brackets. Furthermore, the second storage container is arranged on the flange sliding surface formed by the upper end of the side wall of the first storage container. The second storage container has a pair of rollers at the front of the two side walls, and a pair of protrusions protruding from the side walls at the rear. The pair of rollers and the pair of protrusions of the second storage container are in contact with the flange sliding surface of the first storage container.

In the refrigerator described in Patent Document 1, the contents stored in the first storage container are taken out as follows. First, the first storage container is pulled forward in conjunction with the drawer door. At this time, the second storage container is pulled forward together with the first storage container. In this regard, the user uses his hand to push the second storage container arranged above the first storage container inwardly. In this way, the roller of the second storage container in contact with the flange sliding surface of the first storage container rolls along the flange sliding surface to push the second storage container deeper.

In the refrigerator described in Patent Document 1, a third storage container movable in the front-rear direction is provided above the second storage container. The third storage container is supported by brackets provided on the left and right sides of the storage room. In the refrigerator described in Patent Document 1, the first storage container and the second storage container are pulled out in conjunction with the drawer door, and only the third storage container remains in the refrigerator body. When the user wants to take out the contents stored in the third storage container, the user pulls the third storage container forward along the track with the drawer door open to take out the contents.

However, in the refrigerator described in Patent Document 1, when the items in the first storage container are to be taken in and out, the drawer door is pulled out and the first storage container and the second storage container are pulled out together. The second storage container is in contact with the flange sliding surface of the first storage container and slides toward the rear. At this time, since the second storage container moves on the first storage container while being supported on the first storage container, the forward width of the opening of the first storage container is limited. As a result, there is a problem of inconvenience in accessing and placing items on the deep side of the first storage container.

On the other hand, for example, in the refrigerator described in Patent Document 2, rails for storing the second storage container in the storage room are separately provided on the left and right side surfaces of the storage room. When the user opens the drawer door, the second storage container will be pushed into the deep side along the track. Thereby, the second storage container moves from above the first storage container to the rail and can be moved to a position where it is completely stored in the refrigerator body.

[Problem to be solved by the invention]

The refrigerator described in Patent Document 2 has three types of rails on the left and right side walls of the storage compartment: a lower rail that supports the bracket of the drawer door; a middle rail that supports the second storage container; and an upper rail that supports the third storage container. In such a structure, since three types of rails must be arranged vertically and separately on the left and right side walls of the storage room, the lower rail coupled to the bracket is arranged below the storage room. Therefore, a large distance in the height direction occurs between the position of the handle arranged on the upper part of the drawer door and the fixed position of the bracket provided on the inner surface of the drawer door.

As a result, when the user operates the handle of the drawer door, a high rotational moment will be generated at the fixed position of the handle of the drawer door and the bracket. Therefore, in order to suppress the shaking of the drawer door and to suppress the deformation of the fixing portion of the bracket, it is necessary to take measures such as enlarging the bracket or increasing the plate thickness of the bracket. In order to avoid taking these measures, it is preferable to adopt a structure in which there is no large difference in the height direction between the position of the handle of the drawer door and the fixed position of the bracket of the drawer door.

The present disclosure was developed to solve the above-mentioned problems, and its purpose is to provide a low-cost refrigerator with smooth access and good freedom of use, which can maintain the freedom of use of storage containers stored in the storage compartment while lowering the drawer door. The difference in the height direction between the position of the handle and the fixed position of the drawer door bracket prevents the drawer door bracket from increasing in size and plate thickness.

In the following description, the lower storage container is called the "first storage container 20", the middle storage container is called the "second storage container 30", and the lower storage container is called the "third storage container 40". .

First, the structure of the refrigerator 100 will be briefly described. The structural details of the refrigerator 100 will be described later.

As shown in FIG. 5 , fixed rails 14 extending in the Y direction are respectively provided on the left and right side walls of the refrigerator body 1 (specifically, the left and right side walls of the freezer compartment 4 ). The left and right side walls of the refrigerator body 1 (specifically, the left and right side walls of the freezer compartment 4) are formed by the inner box 51. The fixed rail 14 is also called the "first support part". In addition, the second support portion 17 is arranged in the upward direction Z1 in the Z direction with respect to the fixed rail 14 . The second support portions 17 are also respectively extended along the Y direction and provided on the left and right side walls of the freezing chamber 4 . The fixed rail 14 and the second support part 17 are arranged apart from each other and parallel or substantially parallel.

On the other hand, as shown in FIG. 1 , the door 11 is arranged parallel to the XZ plane and is arranged at the opening of the freezing chamber 4 . In addition, as shown in FIG. 6 , the door 11 has a pair of left and right brackets 12 . The left and right brackets 12 are rectangular plate-shaped members and are respectively extended in the Y direction. The left and right brackets 12 are arranged facing each other. The left and right brackets 12 are arranged parallel to each other. In addition, the height positions of the left and right brackets 12 are the same. As shown in FIG. 4 , the brackets 12 are respectively fixed on the inner surfaces 11 a of the doors 11 . Therefore, the bracket 12 extends from the inner surface 11a toward the inside of the freezing compartment 4 in a direction intersecting the inner surface 11a. Furthermore, as shown in FIG. 6 , the bracket 12 has a bent portion 12 a and a roller 13 . The bent portion 12a is arranged at the lower end along the longitudinal direction of the bracket 12 . The roller 13 is arranged at the end 12b on the deep side of the bracket 12. When the bent portion 12a and the roller 13 of the bracket 12 are arranged in the recessed portion 14a of the fixed rail 14, they contact and slide in the recessed portion 14a of the fixed rail 14 according to the guidance of the fixed rail 14.

In addition, as shown in FIG. 6 , the side part 20b of the first storage container 20 has a first flange part 21. The first flange portion 21 is supported by the bracket 12 and therefore moves in the Y direction in conjunction with the opening and closing operation of the door 11 . Thereby, the first storage container 20 moves in the Y direction in accordance with the opening and closing operation of the door 11 . In addition, as shown in FIG. 6 , the first storage container 20 has a support surface 23 that supports the second storage container 30 .

In addition, as shown in FIG. 6 , the second storage container 30 has a step portion 31 and a second flange portion 33 arranged above the step portion 31 . The step portion 31 is placed on the support surface 23 of the first storage container 20 and is supported by the support surface 23 of the first storage container 20 . Thereby, the second storage container 30 moves in the Y direction together with the first storage container 20 in accordance with the opening and closing operation of the door 11 . Furthermore, when the user wants to take out the contents stored in the first storage container 20, the second storage container 30 is pushed in the back direction Y2 in the Y direction. At this time, the second flange portion 33 of the second storage container 30 is in contact with the support surface 23 and slides. In this way, the second flange portion 33 of the second storage container 30 in the pushed-back state is supported by the second support portions 17 (see FIG. 5 ) provided on the left and right side walls of the freezing chamber 4 .

Furthermore, the third storage container 40 is provided with third protruding portions 41 on the left and right side portions 40b. The third protruding portion 41 is in contact with the upper surface of the step portion 31 of the second storage container 30 and is placed thereon. The first protrusion 36 and the second protrusion 37 are provided on the upper surface of the step portion 31 of the second storage container 30 . The first protrusion 36 restricts the movement of the third protrusion 41 in the Y direction. The third protrusion 41 is fitted between the first protrusion 36 and the second protrusion 37 . Thereby, the third storage container 40 moves in the Y direction together with the first storage container 20 and the second storage container 30 in accordance with the opening and closing operation of the door 11 . Moreover, when the user wants to take out the contents stored in the second storage container 30, he only pushes the third storage container 40 in the back direction Y2 in the Y direction. At this time, with the user's pushing force, the third protruding portion 41 of the third storage container 40 will pass over the second protruding portion 37 provided on the upper surface of the step portion 31 of the second storage container 30 . Furthermore, the side part 40b of the third storage container 40 has a third flange part 43. When the third flange portion 43 is in contact with the second support portion 17 provided on the left and right inner walls of the refrigerator body 1 and slides, the third storage container 40 moves in the back direction Y2 in the Y direction.

In Embodiment 1, a handle 11b is provided on the upper part of the door 11, and the handle 11b is a user's grip when opening and closing the door 11. In addition, in Embodiment 1, two kinds of rails, the fixed rail 14 and the second supporting part 17 as the "first support part" are provided on the left and right inner walls of the refrigerator body 1 . On the other hand, in Patent Document 2 mentioned above, three types of rails are provided. In Patent Document 2, the three types of rails must be arranged separately in the vertical direction, so the lower rail must be arranged very below the storage room. As a result, the distance in the height direction between the bracket that slides in contact with the lower rail and the door handle increases. Therefore, when the door is pulled out, a high rotational moment is generated between the bracket and the door handle. On the other hand, in Embodiment 1, the types of rails can be reduced, and therefore the position of the fixed rail 14 of the lower rail can be increased. Thereby, the distance L1 in the height direction between the bracket 12 which slides in contact with the lower rail and the handle 11B of the door 11 can be reduced (see FIG. 6 ). As a result, the generation of rotational moment can be suppressed, thereby avoiding an increase in the size of the bracket 12 installed on the door 11 and an increase in the plate thickness of the bracket 12, thereby reducing the manufacturing cost of the refrigerator 100.

Hereinafter, the structure of the refrigerator 100 will be described in detail using FIGS. 3 to 8 .

The cross-sectional view of FIG. 7 shows a state in which the first storage container 20 , the second storage container 30 , and the third storage container 40 are stored in the freezing chamber 4 . The cross-sectional view of FIG. 7 shows a cross-section of the refrigerator 100 when the refrigerator 100 is cut perpendicularly with a virtual plane passing through the second flange portion 33 of the second storage container 30 and the third protruding portion 41 of the third storage container 40 . In addition, FIG. 8 shows an enlarged view of the area A of FIG. 7 .

As shown in FIG. 6 , a pair of left and right brackets 12 that are pulled out when the door 11 is opened is fixed to the inner surface 11 a of the door 11 . An example of the material of the bracket 12 is Steel Plate Cold Commercial (SPCC). The left and right brackets 12 are fixed to the inner surface 11a of the door 11 in a cantilever manner. Therefore, the rear end portions 12b of the left and right brackets 12 serve as free ends. The installation method of the bracket 12 is not particularly limited. For example, a screw hole is provided in the bracket 12 , a bolt is inserted into the screw hole, and the front end of the bolt is fixed with a nut. The left and right brackets 12 are respectively elongated plate-shaped members extending in the Y direction. The left and right brackets 12 are arranged facing each other and parallel to each other. The bracket 12 is a support member that supports the first storage container 20 . The rear end of the free end of the bracket 12 is provided with a bracket connection portion 55 that connects the two brackets 12 to each other. As shown in FIG. 6 , the bracket connection part 55 has a first bracket connection part 55a, a second bracket connection part 55b, and a third bracket connection part 55c. The first bracket connection part 55a and the second bracket connection part 55b are respectively installed on the left and right brackets 12 and extend downward. The third bracket connection part 55c is between the first bracket connection part 55a and the second bracket connection part 55b. The first holder connection part 55a and the second holder connection part 55b are connected. The bracket connection part 55 is formed by bending a thin rod-shaped member, for example. The third bracket connection portion 55 c located at the center portion of the bracket connection portion 55 extends in a direction intersecting the extending direction of the left and right brackets 12 . The bracket connection portion 55 is installed at the inner lower portion of the end portion on the back side in the Y direction of the left and right brackets 12 . Furthermore, rollers 13 are installed at the outer lower portions of the rear end portions 12b of the left and right brackets 12 in the Y direction. The installation method of the roller 13 is not particularly limited. For example, a thread portion with male threads is provided before the roller 13, the thread portion is inserted into the thread hole formed in the bracket 12, and a nut is used to fix the front end of the thread portion. . In addition, the lower end of the bracket 12 is provided with a bent portion 12a. The bent portion 12a protrudes outward (left-right direction) from the lower end of the bracket 12 . The left and right brackets 12 and the bracket connection parts 55 are also collectively referred to as the "support frame 120".

The first storage container 20 is placed on the bracket 12 of the door 11 . The first storage container 20 has a bottomed box shape having a rectangular parallelepiped shape with an upper surface open. The first storage container 20 is a first storage container body 20a having an upper surface opening. The first storage container body 20a has a pair of left and right side parts 20b, a back part 20c, a front part 20e, and a bottom plate 20f (see FIG. 7). The pair of left and right side portions 20b face each other. The back portion 20c and the front portion 20e face each other.

Furthermore, the first flange portion 21 is provided on the outer surface 20b1 of the left and right side portions 20b. The first flange portion 21 is disposed near the opening of the first container body 20a, that is, above the outer surface 20b1 of the left and right side portions 20b. The left and right first flange portions 21 respectively protrude outward (left-right direction) in directions away from each other from the outer surface 20b1. Furthermore, the longitudinal direction of the first flange portion 21 extends in the Y direction. The first flange portion 21 may be provided to cover the entire length of the outer side surface 20b1, or may be provided to only a portion of the entire length of the outer side surface 20b1 in the Y direction as shown in FIG. 6 . The first flange portion 21 is supported by the bracket 12 of the door 11 . Therefore, the first storage container 20 moves in the front-rear direction (Y direction) along with the opening and closing operation of the door 11 . The first storage container 20 is placed on the bracket 12 from above. In this way, the first storage container 20 is detachably supported by the bracket 12 and the door 11 .

In addition, as shown in FIG. 6 , the height of the back portion 20 c of the first storage container 20 is set slightly lower than the left and right side surfaces so as to be at a height that does not collide with the second storage container 30 . Moreover, the back surface part 20c of the 1st storage container 20 has the rear stopper part 20d. The rear stopper 20d is in contact with a later-described protrusion 35 provided on the second storage container 30 to restrict the rearward movement of the second storage container 30. The height of the rear stopper 20d is slightly higher than the back portion 20c.

In addition, the height of the first flange portion 21 is slightly lowered near the connection portion between the left and right side portions 20b and the back portion 20c and at the back portion 20c so as to be at a height that does not collide with the second storage container 30 . For example, the gap between the vicinity of the connection portion between the first flange portion 21 and the back portion 20c and the second storage container 30 is about 5 mm.

Furthermore, as shown in FIG. 6 , the left and right side portions 20b of the first storage container 20 are provided with supporting surface portions 23 for supporting the step portions 31 of the second storage container 30 described later. The supporting surface portion 23 protrudes outward from the left and right side portions 20b of the first storage container 20 in a direction away from each other.

Alternatively, the third protrusion part 41 and the fourth protrusion part 42 may also be integrally formed with the third storage container body 40a and the second storage container body 30a.

In addition, the third storage container 40 has a third flange portion 43 provided at the upper end of the left and right side portions 40b. Furthermore, the third storage container 40 has the fifth protrusion part 44 and the sixth protrusion part 45 arranged below the third flange part 43 . The fifth protruding portion 44 and the sixth protruding portion 45 are arranged along the lower end of the third flange portion 43 and arranged below the third flange portion 43 . The fifth protruding portion 44 and the sixth protruding portion 45 are respectively provided on the front side and the rear side along the lower end of the third flange portion 43 . Specifically, the fifth protruding portion 44 is arranged on the front side in the Y direction relative to the sixth protruding portion 45 . Therefore, the fifth protrusion 44 is a protrusion on the front side, and the sixth protrusion 45 is a protrusion on the rear side. The fifth protrusion 44 and the sixth protrusion 45 extend from the lower end of the third flange 43 toward the downward direction Z2 in the Z direction. When the third storage container 40 is pushed backward and stored in the freezer compartment 4 , the fifth protrusion 44 and the sixth protrusion 45 contact the second support part 17 and slide.

The third flange portion 43 of the third storage container 40 is arranged at the upper end of the left and right side portions 40b and extends in the Y direction. In addition, the third flange portion 43 has a width that expands in the left-right direction. When the door 11 is in an open state and the third storage container 40 is stored in the freezing chamber 4, the third flange portion 43 is located on the second support portion 17. On the other hand, when the third storage container 40 is placed in the second storage container 30, regardless of the opening and closing state of the door 11, as shown in FIG. 3, the third flange portion 43 is located at the rear flange of the second storage container 30. Part 39 above. When the third flange portion 43 is placed on the rear flange portion 39 of the second storage container 30 , the third flange portion 43 is located above the second flange portion 33 of the second storage container 30 in the Z direction.

Furthermore, the third storage container 40 is installed on the second storage container 30 so that the third flange portion 43 is located directly above the rear flange portion 39 of the second storage container 30 . At this time, a gap of about 1 mm is generated between the third flange portion 43 and the rear flange portion 39 of the third storage container 40 . Therefore, friction does not occur between the third flange portion 43 and the rear flange portion 39. Therefore, when the third protrusion portion 41 contacts the step portion 31 and slides, the occurrence of unnecessary friction can be suppressed.

In addition, as shown in FIG. 6 , the second storage container 30 is provided with an upper side surface portion 34 above the step portion 31 . The upper side portion 34 is arranged between the step portion 31 and the rear flange portion 39 . When the third storage container 40 is supported by the second storage container 30 , the left and right side portions 40 b of the third storage container 40 are arranged inside the upper side portion 34 . In addition, when the first storage container 20 is pulled out from the freezing chamber 4 and the second storage container 30 and the third storage container 40 are both located in the freezing chamber 4, the second flange portion 33 and the third flange portion 43 are removed together. The second support part 17 supports. Specifically, the second flange part 33 is placed on the second support part 17, and the third flange part 43 is placed on the rear flange part 39, so the third flange part 43 is indirectly supported by the third flange part 39. 2 support department 17 support.

If the second storage container 30 and the third storage container 40 are configured in this way, the third storage container 40 can enter and exit the freezing chamber 4 together with the second storage container 30 when the door 11 is opened and closed. In addition, when the user exerts force to make the third protrusion 41 of the third storage container 40 pass over the second protrusion 37 at the rear of the second storage container 30 and push the third storage container 40 backward, the third protrusion 41 of the third storage container 40 will The third protrusion 41 will pass over the second protrusion 37 . Thereby, the third storage container 40 can be brought into contact with the second support portion 17 and slide to move backward. At this time, the second support part 17 and the third flange part 43 will be in contact.

After sliding, the third protruding portion 41 of the third storage container 40 will fit into the recessed portion 38 of the second storage container 30 to inhibit the third storage container 40 from further moving backward.

Furthermore, the user lifts the third storage container 40, releases the coupling between the third protruding portion 41 and the recessed portion 38, and slides the third storage container 40 further backward. At this time, the fifth protruding portion 44 and the sixth protruding portion 45 provided below the third flange portion 43 will contact the second supporting portion 17 and slide. Thereby, the entire third storage container 40 will be placed on the second support portion 17 formed on the left and right sides of the freezer compartment 4 . In this way, the third storage container 40 is stored in the freezing compartment 4 in a state supported by the second support part 17 . Since the third storage container 40 is stored in the refrigerator body 1, the opening of the second storage container 30 is fully opened.

When the user wants to close the door 11 and pushes the third storage container 40 rearward in the Y direction, the rear end 46 of the third flange portion 43 of the third storage container 40 is in contact with the left and right sides of the freezer compartment 4 . The rear end of the second support portion 17 formed by the side surface 18 stops. Therefore, the third storage container 40 can be prevented from excessively moving backward and falling off from the second support portion 17 .

As described above, the first storage container 20 and the second storage container 30 suppress the movement in the front-rear direction (that is, the movement in the Y direction) of the second storage container 30 by the contact between the coupling portion 24 and the rib 32b. In addition, the second storage container 30 and the third storage container 40 have the third protrusion 41 fitting between the first protrusion 36 and the second protrusion 37 to suppress the movement of the third storage container 40 in the front-rear direction ( That is, movement in the Y direction). Moreover, since the bracket 12 of the door 11 is coupled with the first storage container 20, as the door 11 is pulled out, the third storage container 40, the second storage container 30 and the first storage container 20 can be pulled out together.

Furthermore, when the user wants to access the contents of the third storage container 40 or the contents in front of the second storage container 30 , he only needs to open the door 11 . On the other hand, when the user wants to access the contents at the rear of the second storage container 30, he only needs to push the third storage container 40 backward. Furthermore, when the user wants to access the contents of the first storage container 20, he only needs to push the second storage container 30 backward. Since the third storage container 40 is placed on the second storage container 30, when the second storage container 30 is pushed backward, the second storage container 30 and the third storage container 40 move backward simultaneously. Thereby, the opening of the first storage container 20 is brought into an open state.

In addition, when the second storage container 30 and the third storage container 40 are pulled out, if the third storage container 40 is pushed backward, the third protrusion 41 of the third storage container 40 is embedded in the second storage container 30 The recessed portion 38 is formed, so the rearward movement of the third storage container 40 will temporarily stop behind the second storage container 30 . In this state, the third storage container 40 is within reach of the user's hand.

Similarly, when the second storage container 30 and the third storage container 40 are pulled out, if the second storage container 30 is pushed backward, because the protrusion 35 of the second storage container 30 is in contact with the rear side of the first storage container 20 The stopper 20d is coupled, so the rearward movement of the second storage container 30 will temporarily stop behind the first storage container 20. In this state, the second storage container 30 is within reach of the user's hand.

In this way, when the third storage container 40 or the second storage container 30 is pushed backward, the third storage container 40 or the second storage container 30 will temporarily stop behind the storage container arranged on the lower side of each storage container and be located. The range within reach of the user's hands. Therefore, when the user wants to access the contents of the third storage container 40 or the second storage container 30 , the user can pull out the third storage container 40 or the second storage container 30 again.

According to the above configuration, in the refrigerator 100 according to Embodiment 1, the support portions arranged on the left and right side surfaces 18 of the freezing compartment 4 and extending in the Y direction are both the fixed rail 14 and the second support portion 17 as the first support portion. track, and the above-mentioned conventional refrigerator is provided with three supporting parts. Therefore, compared with the conventional refrigerator, the position of the fixed rail 14 located on the lower rail can be raised, so the vertical distance between the handle arranged on the upper front part of the door and the door bracket can be shortened. Thereby, when the door 11 is opened and closed, the rotational moment generated between the handle 11 b of the door 11 and the fixed part of the bracket 12 can be reduced. Therefore, the direction in which the door 11 is pulled out is close to the direction in which the user exerts force to pull the door 11, so that the door 11 and the bracket 12 will not shake. As a result, the first storage container 20, the second storage container 30, and the third storage container 40 can be pulled out smoothly. In addition, since the bracket 12 will not bear unreasonable rotational torque, the load on the fixed portion of the fixing bracket 12 and the door 11 can be reduced. As a result, it is possible to avoid an increase in the size of the bracket 12 and an increase in the thickness of the bracket 12 .

Furthermore, in Embodiment 1, since the storage container is divided into three stages, the degree of freedom of use of the storage container stored in the freezing chamber 4 serving as the storage room is maintained. In this manner, according to Embodiment 1, the manufacturing cost of the refrigerator 100 can be suppressed while maintaining the degree of freedom of use provided by smooth access to and from the storage containers stored in the freezer compartment 4 serving as the storage compartment.

In addition, in Embodiment 1, the third storage container 40 and the second storage container 30 may be formed of a transparent material, that is, a light-transmitting material. At this time, the user can grasp the contents of the storage items stored in the third storage container 40 and the second storage container 30 at a glance. Therefore, it is preferable that the third storage container 40 and the second storage container 30 are each formed of a transparent material. At this time, the third storage container 40 and the second storage container 30 are formed to contain a light-transmissive resin, for example.

Implementation type 2. 9 is a perspective view showing the structure of a third storage container provided in the refrigerator according to Embodiment 2. In Embodiment 2, the same parts as in Embodiment 1 are denoted by the same reference numerals and descriptions are omitted, and only different parts are described.

The third storage container 40 provided in the refrigerator 100 of the second embodiment is provided with two sliding members 47 instead of the third protruding portion 41 and the fourth protruding portion 42 of the first embodiment. The sliding member 47 is formed of a material different from the second storage container 30 of the middle storage container. The other configurations are the same as the implementation type 1.

On the other hand, the mounting portion 49 is integrally formed with the outer surface 40b1 of the side portion 40b of the third storage container 40. Therefore, the mounting portion 49 is made of a resin member made of the same material as the second storage container 30 and the third storage container 40 .

As described in Embodiment 1 above, when the third storage container 40 and the second storage container 30 are made of the same resin transparent material, the contents can be grasped at a glance. However, at this time, the third protrusion 41 and the fourth protrusion 42 of the third storage container 40 are made of the same material as the second storage container 30 , so that the third protrusion 41 of the third storage container 40 is in contact with the third protrusion 41 . The second storage container 30 slides up. When members that slide in contact with each other are made of the same material, the friction force (friction coefficient) increases compared to when they are made of different materials.

In contrast, in Embodiment 2, the sliding member 47 made of a material different from that of the second storage container 30 is inserted into the mounting portion 49 of the third storage container 40 and installed therein instead of the third storage container 40 . Three protrusions 41 and a fourth protrusion 42 . Thereby, the friction force (or friction coefficient) between the sliding member 47 of the third storage container 40 and the second storage container 30 can be reduced. Here, compared with when the sliding member 47 and the second storage container 30 are made of the same material, the friction force (or friction coefficient) can be reduced simply by being made of different materials. However, the material combination of the sliding member 47 and the second storage container 30 is preferably a material combination that reduces friction (friction coefficient) as much as possible. Examples of the material of the sliding member 47 include POM (Polyoxymethylene, polyoxymethylene) material with good sliding properties.
